Mysterious particles in Saturn's atmosphere may have been shed by the gas planet's rings, according to data from the Cassini spacecraft and presented by researchers at a conference this week.

What they saw: Before Cassini (rest in peace) plummeted into Saturn last month, the spacecraft made several dives through the planet's outer atmosphere. A mass spectrometer on board detected large, complex molecules in the planet's atmosphere — including methane, carbon dioxide and more complex molecules, reports Alexandra Witze for Nature. The researchers believe the particles came from the rings because they were most common around the planet's equator and high altitudes.

Why it matters: The voyage allowed them to test long-standing hypotheses about the composition of Saturn's atmosphere. By studying planets in the outer solar system, we can learn more about how our corner of the cosmos formed.

Dunkin' Brands, operator of both Dunkin' Donuts and Baskin-Robbins, agreed on Friday to be taken private for nearly $11.3 billion, including debt, by Inspire Brands, a restaurant platform sponsored by private equity firm Roark Capital.

Why it matters: Buying Dunkin’ will more than double Inspire’s footprint, making it one of the biggest restaurant deals in the past 10 years. This could ultimately set up an IPO for Inspire, which already owns Arby's, Jimmy John's and Buffalo Wild Wings.

Federal judge halts Trump administration limit on TikTok

A federal judge on Friday issued an injunction preventing the Trump administration from imposing limits on the distribution of TikTok, Bloomberg reports. The injunction request came as part of a suit brought by creators who make a living on the video service.

Why it matters: The administration has been seeking to force a sale of, or block, the Chinese-owned service. It also moved to ban the service from operating in the U.S. as of Nov. 12, a move which was put on hold by Friday's injunction.
